I think it was Dennis Jensen who worked out that in order to get the electric blower to operate at a level that would create any kind of improvement at all (so small you probably wouldn't even feel it with your butt-o-meter), it would take 5 alternators. We can drive those 5 alternators using fairy wishes, but most people will have to resort to using the engine to drive them.

And of course, some of the gravitational potential energy stored in the car at the top of a hill is used to actually get the car down the hill :-)
